Aldeyra Therapeutics Provides Regulatory Update on ADX-2191
U.S. Food & Drug Administration(FDA) Determination of Lack of Adequate and Well Controlled Investigations in the Scientific Literature, Complete Response Letter Received for New Drug Application (NDA) of ADX-2191 (methotrexate injection, USP) for the Treatment of Primary Vitreoretinal Lymphoma (PVRL)
- Due to Shortage of Methotrexate, Lack of Approved Therapy for PVRL, and Inbound Requests for ADX-2191, Expanded Access Program Planned to be Discussed with FDA
“While we appreciate the FDA’s position with respect to providing evidence from adequate and controlled trials, we do not currently believe that randomized clinical trials of ADX-2191 in PVRL, a rare and fatal cancer with no approved therapy, are feasible,” stated
PVRL is a rare, high-grade, aggressive cancer, with a median survival of less than five years.1 Methotrexate, the compounded intravitreal injection of which is the standard of care for the treatment of PVRL,2 is currently in shortage, per the FDA Drug Shortages database. An Expanded Access Program allows for access to treatment options for serious diseases when other therapeutic options are not available. Aldeyra plans to discuss ADX-2191 for the treatment of PVRL with the FDA, including the potential to make ADX-2191 accessible to PVRL patients under an Expanded Access Program protocol.
ADX-2191 is also under development for the treatment of proliferative vitreoretinopathy and retinitis pigmentosa, both of which are rare, sight-threatening retinal diseases. Top-line results from a Phase 2 clinical trial of ADX-2191 in retinitis pigmentosa are expected to be announced in June of 2023. Additionally, Aldeyra plans to conduct a Type C meeting with the FDA in the second half of 2023 to discuss the completion of clinical development of ADX-2191 for the prevention of proliferative vitreoretinopathy.
